229-L Water Matric Potential Sensor
|
The 229-L Water Matric Potential Sensor measures soil water potential from 0.1 to 10 bars. The sensor consists of a heating... |
227-L Soil Matric Potential Block
|
The 227 estimates soil water potential from 0.1 to 10 bars. When the 227-L is wet, electrical resistance is low. As... |
223-L Soil Matric Potential Block
|
The 223-L estimates soil water potential from 0.1 to 10 bars. It is identical to the 227-L but configured for use... |
253-L Soil Matric Potential Block
|
The 253 (also known as the Watermark 200) provides a convenient method of estimating soil water potential between 0 and -2... |
257-L Soil Matric Potential Block
|
The Watermark 200 provides a convenient method of estimating soil water potential between 0 and -2 bars (typically wetter, or irrigated... |
About Soil Water Potential Sensors
Soil water potential sensors determine the energy status of water in soil. The energy state describes the force that holds the water in the soil. We offer sensors to measure soil water potential by two methods: the heat dissipation method or the electrical resistance method.
